Subject: Fix PR18374 by making readelf and objdump ignore end-of-list markers
 in the .debug_loc section if there are relocations against them.

	PR binutils/18374
bin	* dwarf.h (struct dwarf_section): Add reloc_info and num_relocs
	fields.
	(struct dwarf_section_display): Change bitfield to boolean.
	(reloc_at): Add prototype.
	* dwarf.c (display_loc_list): Ignore list terminators if there are
	relocs against them.
	(display_debug_loc): Issue a warning if there are relocs against
	the .debug_loc section.
	(display_displays): Initialise reloc_info and num_relocs fields.
	* objdump.c (load_specific_debug_section): Initialise reloc_info
	and num_relocs fields.
	(reloc_at): New function.
	* readelf.c (is_32bit_abs_reloc): Add IA64's R_IA64_DIS32LSB
	reloc.
	(reloc_at): New function.
	(apply_relocations): Add relocs_return and num_relocs_return
	parameters.  Fill them in with the loaded relocs if non-NULL.
	(dump_section_as_bytes): Update call to apply_relocations.
	(load_specific_debug_section): Initialise reloc_info and
	num_relocs fields.

tests	* binutils-all/pr18374.s: New test file.
